论文摘要
我们提出了一种快速可靠的方法，用于切割2D材料，以创建2D扭曲的异质结构和设备。我们证明了使用锥形纤维鳞片切割石墨烯的有效性。电运输测量显示了使用我们的技术制造的石墨烯层之间所需扭曲的证据。将使用我们方法的成功扭曲堆栈数量的统计数据与H-BN辅助撕裂和堆栈方法进行了比较。同样，我们的方法可用于扭曲的材料构造很少的纳米厚度。最后，我们证明了锥形纤维的多功能性，用于敏感2D材料的其他相关应用。
We present a quick and reliable method to cut 2D materials for creating 2D twisted heterostructures and devices. We demonstrate the effectiveness of using a tapered fibre scalped for cutting graphene. Electrical transport measurements show evidence of the desired twist between the graphene layers fabricated using our technique. Statistics of the number of successfully twisted stacks made using our method is compared with h-BN assisted tear-and-stack method. Also, our method can be used for twisted stack fabrication of materials that are few nanometers thick. Finally, we demonstrate the versatility of the tapered fibre scalped for other shaping related applications for sensitive 2D materials.
